As it turned out the A5 wasn't nearly as far out of the way as I had expected - because the A43 was shut north of Brackley (for resurfacing?) so you had to go that sort of way anyway (Buckingham, Old Stratford, A508. Shame, I enjoy the roundabouts on the Brackley bypass, although they need some care in the wet.
Anyway, Super Sausage foodrep - Went for the large brekkie and two cups of coffee. Bacon not fried as crispy as I like, but they were nice thick slices. Sausages good, black pudding ok for southerners, beans, mushrooms and eggs fine. Would prefer the plum tomatoes in a bit of sauce, but that's a very minor quibble. Plenty of toast. Only serious problem was the fried bread. Don't think it was done deep fried in proper lard.
Overall, a solid 7 or 8 out of 10. Completely stuffed on leaving and didn't need to eat anything else till I got home around 8pm. Nice and solid this morning too, though that's probably more info than needed for a food review.
